Summary
Vesugen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for blood vessels and the vascular endothelium. It supports endothelial cell function, promotes vascular wall integrity, and is studied for atherosclerosis prevention, vascular aging, and cardiovascular health maintenance. It is one of the more broadly applicable Khavinson bioregulators given the ubiquity of vascular tissue.
P21 is a synthetic peptide derived from CNTF (ciliary neurotrophic factor) that promotes hippocampal neurogenesis, enhances memory and spatial learning, and may reduce amyloid-beta pathology. It is used as a neurogenic and cognitive enhancer with potential anti-Alzheimer's applications.
